When architects, lighting specifiers, contractors and developers select recessed LED downlights for modern buildings, they often face two recurring challenges: achieving a consistent ceiling appearance across different finishes, and choosing lighting products that can accommodate changing dimming, colour-tuning and smart-control requirements. Using separate luminaire families for each installation or control scenario can also increase specification work, stock complexity and installation time.
The Lediant Prime Series modular LED downlight platform is designed to address these needs with one shared optical and thermal core and a choice of interchangeable trims and configurations. The range includes fixed, tilt and trimless versions, multiple ceiling cutout sizes and compatibility with DALI DT6, DALI DT8 and Casambi control solutions. This modular approach helps architects, interior designers, M&E engineers, lighting contractors and distributors specify a consistent recessed downlight solution for residential, hospitality, retail and office projects across Europe.
Visual comfort is central to the Prime Series design. Its deep anti-glare construction delivers UGR < 19, helping to reduce uncomfortable glare in spaces where people spend extended periods. An optional dedicated UGR < 19 accessory is also available for projects that require additional glare control. The low-glare performance is integrated into the optical design rather than treated as an afterthought.
The downlight uses high-performance COB LED chips and a precision-engineered die-cast aluminium housing. The aluminium structure supports heat dissipation, helping to maintain stable colour performance and reliable operation over the product's service life, including in applications with extended operating hours.
Instead of specifying separate product families for fixed, adjustable or plaster-in ceiling applications, the Prime Series uses a universal module concept. Interchangeable trims allow the appearance to be adapted while retaining the same core light engine. Fixed, tilt and trimless configurations are available to suit different ceiling designs, while multiple cutout options support both new installations and retrofit projects with existing ceiling openings.
The platform is standardised around 8W and 10W power options, delivering 800–900 lm. This output range balances practical illumination for general ambient and accent lighting with low energy consumption.
A consistent technical specification across the four Prime variants makes the platform easier to compare and specify. All models support dimming and offer CRI options of 80, 90 and 95+, allowing the light source to be selected for general functional lighting or applications where accurate colour rendering is important, such as retail, galleries and premium hospitality. A power factor of PF 0.9 supports stable operation on commercial electrical circuits.
For projects in the UK and France, the Prime Series is fire rated and insulation coverable. The luminaire can be covered with loose-fill or blown insulation materials, removing the need for separate insulation guards and helping simplify installation in insulated ceilings. Always refer to the relevant product documentation and project requirements when confirming suitability for a specific ceiling construction.
For humid indoor environments, the front face is rated IP65 and the rear is rated IP50. This makes the range suitable for specified bathroom zones, kitchen areas and other humid indoor applications, subject to the installation location and applicable local requirements.
The Prime Series offers configurable light distribution to support different lighting effects. Lens optics provide a 40° beam angle, while reflector options provide a 45° beam angle. The tilt version offers up to 20° aiming adjustment, enabling light to be directed towards display surfaces, artwork, architectural details and retail merchandise.
A front-selectable 3CCT switch provides 2700K, 3000K and 4000K colour temperature options. Installers can select the preferred white light colour on site, reducing the need to order and hold separate fixed-CCT versions for different project requirements.
The range is specified as complying with the RT2012 and RE2020 thermal requirements stated for relevant French low-energy building projects, and is backed by a 5-year warranty. Project teams should confirm the applicable compliance documentation for the exact product configuration and project.
The Prime Universal Modular IP65 BBC Downlight is the versatile all-rounder in the range. It offers three interchangeable reflector geometries—D shape, U shape and V shape—to create different light distributions for ambient, directional or layered lighting. A wide 10 mm trim or slim 4 mm trim can be selected to suit the desired ceiling appearance.
Dimensions: fixed version; cutout 68–70 mm; housing Ø76 × H69 mm.
Typical applications: hotel guest rooms, corridors, shared apartment areas, retail back-of-house spaces, bathroom zone 2 and general commercial interiors. Its BBC-compliant and insulation-coverable design makes it suitable for consideration in French new-build and renovation projects.
The Prime Trimless Modular Downlight is designed for minimalist interiors that call for seamless ceiling integration. Once plastered in, the fixture sits discreetly within the ceiling plane, avoiding a visible trim ring and supporting clean, uninterrupted ceiling designs.
Dimensions: fixed version; cutout 68–75 mm; housing Ø69 × H70.6 mm.
Typical applications: luxury residential interiors, high-end show apartments, boutique hotel lobbies, modern office meeting rooms, museums and galleries—particularly where ceiling continuity is an important part of the interior design.
The Prime Tilt Modular Downlight adds directional flexibility through up to 20° of adjustment. Installers can aim the light after installation to highlight selected objects or architectural features.
Dimensions: cutout 75 mm; housing Ø83 × H84 mm.
Typical applications: retail shopfronts, display shelving, artwork and feature-wall lighting, restaurant dining areas and reception desks. It is a practical choice when the lighting scheme needs to accent specific objects rather than simply provide general illumination.
The Prime 80–83 mm Cutout Modular Downlight is a larger fixed version for projects with wider existing ceiling openings or designs that call for a slightly larger aperture. It shares the modular core, optical performance and stated compliance features of the wider Prime platform.
Dimensions: fixed version; cutout 80–83 mm; housing Ø88 × H81 mm.
Typical applications: retrofit projects with larger ceiling openings, residential living rooms, open-plan apartments, office breakout areas and shared residential spaces where an 80–83 mm cutout is used.
Every model in the Prime Series is compatible with Lediant's established smart retrofit control ecosystem, including DALI DT6, DALI DT8 and Casambi. This allows a project to retain the same downlight family when control requirements develop from basic dimming to tunable white or wireless lighting control.
DALI DT6 supports precise dimming through professional lighting control systems. DALI DT8 enables colour-temperature adjustment and tunable white lighting. Casambi provides Bluetooth mesh wireless control and can be useful in retrofit projects where installing new control wiring is impractical. Compatibility with these control options can simplify specification, sample evaluation and project handover for teams already working with Lediant smart lighting solutions.
A unified modular LED downlight platform offers benefits throughout the project supply chain. Distributors can reduce SKU complexity by using a shared product platform with different trim and configuration options. Lighting consultants can work from a more consistent specification, while electricians can benefit from a familiar installation approach across different ceiling styles. Building owners and end users also gain flexibility, because control requirements can be upgraded without necessarily changing the luminaire family.
From low-energy residential developments and boutique hotel fit-outs to retail refurbishments and office renovations, the Prime Series is designed to support projects that need low-glare recessed lighting, flexible ceiling integration and smart-control readiness in one modular downlight platform.
Lediant Lighting designed the Prime Series to complement its wider lighting portfolio. Alongside the Tuya RGB ambient downlight range and smart retrofit DALI and Casambi solutions, Prime provides a professional modular downlight platform for projects where visual comfort, installation flexibility, compliance requirements and smart readiness are key considerations.
